Firefox only (Windows/Mac/Linux): Firefox extension Surfkeys scrolls web pages, switches tabs, and executes common browser actions from the comfort of your home row. Once installed, you can scroll web pages using the k (down) and i (up) keys, move to new result pages in Google with m and n, page up and down with p and the semi-colon, and tons more. Surfkeys takes some time getting used to, but if you have a real disdain for your mouse, it's a killer extension. Then again, if you prefer to stick with the Firefox defaults, check out our guide to Firefox without your mouse. Likewise, we wholeheartedly recommend switching to the experimental Google search results via keyboard. Surfkeys is free, works wherever Firefox does.
